What is the element at used for?
Astatine is a dangerously radioactive element. There are currently no uses for astatine outside of research. The half-life of the most stable isotope is only 8 hours, and only tiny amounts have ever been produced.
Where is astatine found?
Astatine can only be found on Earth following the decay of thorium and uranium. It is estimated that less than 30 g of astatine is present in the Earth’s crust, only very few µg of astatine have been produced artificially so far, and elemental astatine has not been viewed by the naked eye due to its instability.
Where is at on the periodic table?
Metals reside on the left side of the table, while non-metals reside on the right. Organizing the elements to help further our understanding was first provided by Dmitri Mendeleev….Periodic Table with Element Names and Electronegativity.
| Element Name | Astatine |
|---|---|
| Symbol | At |
| Atomic Number | 85 |
| Electronegativity (χ) | 2.2 |
What is the price of astatine?
Taaffeite (Between Rs. 1,60,256 To Rs. 12,82,010 per gram)
Where is polonium found?
uranium ores
Polonium is a very rare natural element. It is found in uranium ores but it is uneconomical to extract it. It is obtained by bombarding bismuth-209 with neutrons to give bismuth-210, which then decays to form polonium. All the commercially produced polonium in the world is made in Russia.
How is polonium used?
In commercial applications, polonium is occasionally used to remove static electricity in machinery or dust from photographic film. It can also be used as a lightweight heat source for thermoelectric power in space satellites.
What is CA in the periodic table?
Calcium was named after the Latin term calx meaning lime, and is a reactive silvery metallic element found in Group 2 of the periodic table. It was first isolated in 1808 in England when Sir Humphry Davy electrolyzed a mixture of lime and mercuric oxide.
